Other claims from this paper (12)
- Intervention effect Increased P significantly inhibited the increase in Fe uptake of fe-type soybean.
- Intervention effect Increased P slightly affected the increase in Fe uptake of Fe-type soybean.
- Intervention effect Peanut had a curvilinear response to increasing P, with somewhat lower values at intermediate P than at low or high P.
- Intervention effect Higher chelator:Fe ratios increased the severity of chlorosis of fe-type soybean.
- Intervention effect Lower Fe increased the severity of chlorosis of fe-type soybean.
- Intervention effect Higher P increased the severity of chlorosis of fe-type soybean.
- Intervention effect Higher chelator:Fe ratios had no effect on chlorosis of Fe-type and Wayne-type soybean cultivars.
- Intervention effect Lower Fe had no effect on chlorosis of Fe-type and Wayne-type soybean cultivars.
- Intervention effect Higher P had no effect on chlorosis of Fe-type and Wayne-type soybean cultivars.
- Observation Chlorotic leaves of the soybean fe-type contained less than 40 mg Fe/kg dry weight.
- Method / resource The proposed phosphate-based method selectively screens fe-type soybean from other Fe-efficiency types.
- Mechanism Fe-inefficiency of fe-types is attributed to failure of derepression of the Fe-stress response at environmental phosphate levels.
